Title: Battery charge controller for dual mode vehicle
Inventor: OOMOTO TOSHIYASU
IPC: B60L13/00
Filed: 1979-02-20
Abstract: PURPOSE: To increase the charging efficiency of a battery for a dual mode vehicle by providing charging current control means for controlling the charging current of the battery in the vehicle to automatically charge the battery in response to the residual capacity of the battery.  
     CONSTITUTION: This battery charge controller consists of charging current setting means 9 for flowing a preset current Is in a battery 8 at charging time, charging current detecting means 10 for detecting the charging current Ix supplied to the battery 8 to produce a signal responsive to the detected current and charging current control means 11 for controlling the charging current to the battery 8 to become a relationship of Ix=Is. When the battery starts charging to flow the charging current Ix in the battery, the increasing rate of the charging current through a charging current detector circuit 10b is decreased. When the charging current Ix is thus retained at set value Is, it maintains its state. As the battery 8 is charged increasingly, the charging current Ix is reduced. When the battery is substantially fully charged, a charging current detector circuit 10b produces a charge end signal S to stop charging of the battery. Thus, the battery can be automatically efficiently charged.

Abstract: PROBLEM TO BE SOLVED: To drastically reduce the FFT operation time while maintaining high frequency accuracy by comparing thresholds, where two distances are set, with an obstacle distance and changing the number of FFT(Fast Fourier transform) points or the like. SOLUTION: A beat signal, where a transmission wave to a forward obstacle and a reflection wave are synthesized, is passed through an LPF 7 or the like, and the discrete value data of the beat signal being sampled by an A/D converter 9 using a frequency analysis processor 10 are processed by a frequency analysis method to extract a spectrum. The peak pairing and grouping of the spectrum are made by target recognition equipment 11 and the distance to the obstacle and the relative speed are calculated. A threshold discrimination circuit 12 compares the distance to the closest obstacle with a threshold and changes the sampling frequency of the A/D converter 9 for the beat signal of the next cycle and the number of FFT points used by the frequency analysis processor 10.  Further, the degree of hazard for the obstacle is discriminated from the distance to the obstacle and the relative speed and is reported by an alarm 14.

Abstract: PURPOSE:To eliminate failure accompanying the automatic adjustment of the emitted light quantity of a laser diode (APC) such as the wasteful consumption of toner, the soiling of a transfer part or the fatigue of a photosensitive body by executing the APC while the joining part of the photosensitive body exists at a laser exposure position. CONSTITUTION:When a synchronization mark detection signal is inputted from a synchronization mark detector 11 through an input port 33, an internal timer is started at this time. Then, when the joining part of the photosensitive body arrives at the laser exposure position, the APC is executed. After the laser diode 25 is turned on through a D/A converter 24, a D/A value when the outputs of comparators 29 and 30 respectively become 'H' is saved by increasing a value set to the converter 24 by a CPU 21 by a prescribed value at a time. Then, the APC is finished by turning off the diode 25. When the APC is finished and the joining part of the photosensitive belt arrives at a prescribed position where it is passed through the laser exposure position, the internal timer is reset and printing and writing are started at the same time.

Title: Ink jet printer
Inventor: WATANABE KATSUTO
IPC: B41J2/175
Filed: 1983-02-07
Abstract: PURPOSE:To prepare an accurate and easy unnecessary ink treating means, in an ink jet printer having an ink tank, by providing a detection means for detecting that the ink amount in the ink tank reaches a predetermined amount or more. CONSTITUTION:Because both needle electrodes 36, 37 are arranged so as to be partitioned by the partition wall 31C of a rubber cap 31, the needle electrodes 36, 37 are directly short-circuited by ink splash on a sponge 42 and no erroneous operation is generated. When ink is flowed into a waste liquid tank 30 having this constitution in an amount exceeding a predetermined amount to bring about a full-charged state, the ink allowed to sufficiently impregnate the lower sponge 42 is flooded and the ink level is raised overflowing the upper surface of the sponge 42. When the liquid level of the ink is further raised and reaches the lower end surfaces of the needle electrodes 36, 37 to be contacted therewith, the conductive ink is electrically connected to both needle electrodes to alarm or display the full-charged state. By this mechanism, when the full-charge of the waste liquid tank 30 is detected and an alarm is emitted, said tank 30 is replaced with a new tank main body part which is, in turn, inserted and fixed to the rubber cap 31. By this method, liquid storing is again enabled.
